Very brief indeed. I read the entire book in about 20 minutes. Although it gives some interesting info about the early history of the mark, it greatly suffers from lack of any detail pertaining to Jaguars of the past 30 years, especially those Jaguars still on the road today. As an example, the XK8 suffered from automatic transmission problems from 96-99 that required those transmissions to be replaced during any regular maintenance done at the dealer. No mention was made of this.
This short book, okay for $2.99, reads more like a compilation of Jaguar brochures through the ages rather than a objective viewpoint from an author with no association with Jaguar.
The early history of the mark and the trials and tribulations that Jaguar went through in it's formative years is interesting, but limited in it's scope. For your $2.99 kindle version, it's what you would expect for the money. Would I recommend it? For non-Jaguar enthusiasts that simply want a brief overview, yes. For Jaguar owners who would like an in-depth history of the mark and it's models through the years, I would certainly recommend going elsewhere. There are a lot of good Jaguar books out there, and I recommend those by Nigel Thorley.
